I love looking at and having beautiful things, but I am incredibly cheap. Really. I've found that the perfect way to indulge my desire for flowers on a tight budget is to buy a only few of my favorite stems and place them strategically in bud vases.
Ideally, these stems would always be beautiful peonies or ranunculus (plural, ranunculi?), but I think almost anything looks artistic and elegant when it's on its own in a pretty vase. And maybe it's overkill, but having a single bloom in the bathroom next to the sink always makes me happy.

So classic and elegant, this would be beautiful with white hydrangeas.

I would keep these delicate urchin-inspired beauties as a grouping.

No bud vase? Use a tall shot glass! Just be sure it doesn't scream "spring break in Jamaica," unless that's the look you're going for.

My grandma has these and I think they are really unique. Napkin rings seem to have fallen out of favor as of late (unfortunately), but this is such a fun twist on the tradition.

This is just a beautiful objet. Even a cluster of white carnations would be instantly elevated in this antique.

These have a worn but still refined elegance.

These could go modern or classic depending on the blooms.

Totally wild. Definitely conversation starters.

Buy one for yourself and give one as a hostess gift with a beautiful stem. It's inexpensive, but can have a big impact.
